The Multivalve Piston Technology Leader

Wiseco is world renowned for their work building race winning pistons for sport compact engines featuring small bores, multi-valves and high RPM applications for many years. Wiseco utilizes experience acquired from a diverse background of the most sophisticated engines in such venues as Formula1, Indy Racing League (IRL), NHRA Pro Stock Bike, AMA Superbike, and AMA Motocross to design and manufacture the highest technology Sport Compact piston available.

Valve pocket designs that allow maximum flow around valve, also allowing oversized valves and high lift cams to be utilized.
 
Piston crown shapes designed to promote maximum intake charge efficiency thru scavenging mixture Cross Flow during intake and exhaust valve overlap. More fuel and air equals more horsepower!

Pistons designed to optimize squish or quench during com pression combustion cycle event, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.

Wiseco ‘s complex piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal. Wiseco has added skirt coatings to the long list of standard features on shelf stock Sport Compact pistons!

Precision machined ring grooves with proper orifice/accumulator volume using calculated groove root diameters and axial widths, featuring excellent surface finish and flatness providing maximum ring seal thus minimizing blow-by and oil consumption.

Wiseco’s world class forging facility that utilizes the latest technologies featuring complex forging shapes, advanced materials and features aligned grain flow technology.
